OHIO.

Letters Patent No. 101,692, dated April 5, 1870.

IMPROVEMENT IN BLOW-PIPES.

The Schednle referred to in these Letters Patent and making part of thesame.

To all whom it may concern Be it known that I, L. B. WVILSON, ofCambridge,

in the county of Guernsey` and in the State of Ohio, have inventedcertain new and useful Improvements in'Blow-Ppes; and do hereby declarethat the follow.

In order to enable others skilled in the art to which my inventionappert-a-ins to make and use the same, I will now proceed to describeits construction and operation, in whicll- I Figure 1 is a longitudinalvertical section of' the wick-tube, with the blow-pipe;

Figure 2 is a, longitudinal rerticalsection of' the alcohol-reservoir,with connecting-tube; and

Figure 3 is a side vieiiy of the wick-tube.

A represents the alcohol-reservoir, provided in the center of' itsbottom' with an opening, in which is screwed a. crows-f'oot, B, uponwhich the reservoir rests. I

A tube, a, passes upward, through the rest B, to near the top of thereservoir A, so as to admit air on top of the alcohol.

One of the Afeet of the rest B is hollow, and connected by a. flexibletube, C, with .a small tube, l), extending from the side of thelwick-tube E.

Thewick is inselted in the wick-tube so as to allow the tube to extenda. suitable distance above the wick,

referring to the annexed dra-wings,

andthis projecting part of the tube is slotted on one side, as shown inligs. l and 3.

A small tube, b, conneeted with the blow-pipe G, extends up through thecenter of the wick, whereby the full force of the llame is taken inproducing a far greater heat with less blowing than other blow-pipes nowin use.

The cylinder or wick-tube E, by projecting out over the wick on theupper side, prevents the flame from blazing up out ofthe way of' thetube h, through which the air passes.

lhe amount of nlcohol supplied to the wick is regulated by the set-screw(l in the tube D.

" Haring thus fully described my invention,

What I ela-im ns new, and desire to sev-uri.: hy Letters Patent, is l.Thecylinder or wick-tnbe ll, constructed as de scribed, so ns to extendabove the top ofthe wick,

substantially as and for the purposes herein set forth.

2. Thel arrangement of the tube b of n blow-pipe within the center ofthewick in the 'cylinder E, substnntiallv as and for 'the purposes hereinset forth.

3. The combination und arrangement of the reservoir A, rest B, with tubeil, flexible pipe C, pipe I), with set-screw d, cylinder E, tube l1, andblow-pipe G, all Substantially as und for the purposes herein set forth.

In testimony tha-t I claim the ln'egoing, I have hereunto set myhand andsenl this 30th day of December, ]869.
